Window
Window function enables the display screen to be divided into “windows” each of which can be
controlled and displayed independently.
Display Memory is shared by all windows; individual windows do not have their own display memory.
There are 2 types of “window”: Base-Window and User-Window.
Refer to 4.7.4.43 User Window define / cancel.
Base-Window covers the entire display screen. If no User-Windows are defined, all display
operation is processed on this window. If one or more User-Windows are defined, display operation
on any area not covered by a User-Window is done by selecting Base-Window. When Base-Window
is selected, even if User-Window(s) are defined, all display operation is processed under Base-
Window. Therefore the current display contents of User-Window(s) is overwritten.
Operation on Base-Window depends on the setting of “Write screen mode” (refer to 4.5 Write screen
mode).
User-Window is defined by User-Window definition command. Display operation is processed on the
window selected by Current Window select command.
A maximum of 4 User-Windows can be defined.
